ADJUSTABLE ELITE-RECEIVER.

Specification of Letters Patent.

Patented Nov. 15, 1910.

Application filed February 28, 1910. Serial No. 546,341.

To all whom it may concern:

Be it known that I, JOHN J. MCDONALD, a citizen of the United States, residing at L nn, in the county of Essex and State of Miassachusetts, have invented new and useful Improvements in Adjustable Flue-Receivers, of which the following is a specification.

This invention relates to improvements in flue receivers for chimneys of that class in which the chimney extends up through the walls of the building and is provided with a hole to receive the flue of the stove, the adjacent wall being provided with a larger hole through which the flue extends into the hole in the chimney.

The building laws require that a tube shall be fitted into the hole in the chimney to receive the flue and another tube fitted into the adjacent hole in the wall. There is always more or less shrinking and settling of the walls with relation to the chimney, the amount, of course, being greater at the upper story or stories than at the lower story. In practice, the face of the chimney between the hole in the chimney and the relatively larger hole in the wall is plastered to give it a finished appearance and to close the space between the chimney and the wall at that point. When the wall shrinks and settles it causes the plaster on the face of the chimney to crack and often causes the plaster of the wall itself to crack due to the relative vertical movement of the two tubes just described.

The object of my invention is to provide a flue receiver so constructed as to prevent such cracking of the plaster and providing means to give a neat finished appearance to the face of the chimney between the two holes above described, this object being attained by providing suitable means forming a self-adjusting connection between the tube in the chimney and the tube in the wall, said means permitting relative vertical movement of said tubes as the wall shrinks and settles.

Another object is to provide convenient means to close the aperture of the tube in the chimney hole when there is no stove connected thereto.

The invention consists in the novel features of construction and in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the appended claims.

Referring to the drawing: Figure 1 is a perspective view of an adjustable flue receiver embodying my invention. Fig. 2 is an elevation viewed from the inside of the wall of a house showing the adjustable flue receiver in place. Fig. 3 is a sectional View taken on line 3-3 of Fig. 2, looking toward the right.

Like numerals refer to like parts throughout the several views of the drawing.

In the drawing, 5 is a chimney extending upwardly between two walls 6 and 7 in the usual manner, said chimney being provided with a usual hole 8 for the flue and the wall 7 being provided with a hole 9 relatively larger than the hole 8 as is customary.

Located in the hole 8 is a tube 10 which receives a usual flue 11. Located in the hole 9 is a tube 12 with which a tube 13 is telescopically assembled, the latter tube being preferably provided with a flange 14 resting against the face of the wall 7. I connect the tubes 8 and 12 by suitable means forming a self-adjusting connection between said tubes, whereby relative vertical movement of said tubes is permitted as the wall 7 shrinks and settles. In the present instance, this means consists of a plate 15 formed on or secured to the tube 8 and resting against the face of the chimney 5, said plate having formed thereon or secured thereto in any suitable manner two vertical guides 16, 16 which receive a flange 17 formed on or secured to the tube 12, thus preventing relative horizontal movement of the tube 12 and the plate 15, yet permitting a vertical sliding movement of said tube and said plate. The plate 15 also forms a neat finish for the front face of the chimney between the hole 8 and the hole 9.

In practice, the device is assembled with the center of the hole 9 above the center of the hole 8, as shown in the drawing, a sufficient distance so that shrinking and settling of the wall 7 will bring the hole 9 into approximate co-axial location with the hole 8. Since the amount of vertical movement is different at the different floors of the building, the amount which the two tubes will be offset from each other will vary at the different stories of the building and will be governed by the probable shrinking and'settling of the walls. Thus it will be seen that the device automatically adjusts itself and obviates the difficulties heretofore experienced.

In order that the tube may bewclosedlm tube 12 being cut away for said slide and said guides, as shown. The slide 18 is provided withsuitable frictional means acting to hold the same against vertical movement, such means, in'this instance, consisting of a suitable spring 20 secured to the plate 15 and bearing against the back face of the slide 18.

The slide 18 is )referably provided with a flange 21 adapted to engage the upper side of the periphery of the tube 12, thus limiting the downward movement of said slide and said slide is also provided with a handle 22 by which the same may be moved vertically, said handle also serving as a means for limiting the upward vertical movement of said slide. WVhen the stove is disconnected and the flue 11 removed from its place, the slide 18 is moved into position to close the aperture in the tube 8.

Having thus described my invention, what I claim and desire by Letters Patent to secure 1s:

1. The combination with a chimney and a distinct independent wall separated from each other by an air space, of an apertured plate supported upon said chimney and havmg its rear face disposed against the face of said chimney, a sleeve extending horizontally into said chimney, a sleeve extending horizontally into said wall from the aperture of said plate, and means located on the front face of said plate forming an adjustable connection between said sleeves and permitting relative vertical movement of said chimney and said wall carrying said sleeves respectively therewith.
